David Ok, 21, is accused of walking into two pharmacies on Long Island with a handgun and threatening employees looking for prescription drugs.

Police say both incidents happened on Friday.

The first was in Plainview at the Island Care Pharmacy. Police say Ok walked in with a gun and a black cloth over his face, but when he saw a bullet-proof glass “bandit barrier” protecting the pharmacist, he took then.

Then, police say an hour later, he walked into the Bethpage Medical Pharmacy in Bethpage. Police say with gun in hand and his face covered, he handed the pharmacist a note demanding oxycodone.

He then took off with an unknown amount of pills in a black Volkswagen. No one was hurt.

Police later found the Volkswagen in front of Ok’s home in Westbury and he was arrested.

The 21-year-old is being charged with robbery and criminal use of a firearm. Police are also charging him in a separate incident that happened at the Island Care Pharmacy back in August.
